A method of operating a vehicle, such as an autonomous vehicle, includes the steps of receiving a message from roadside infrastructure via an electronic receiver and providing, by a computer system in communication with said electronic receiver, instructions based on the message to automatically implement countermeasure behavior by a vehicle system. Additionally or alternatively, the method may include the steps of receiving a message from another vehicle via an electronic receiver and providing, by a computer system in communication with said electronic receiver, instructions based on the message to automatically implement countermeasure behavior by a vehicle system.

A braking force control system includes: a brake device and at least one electronic control unit. The brake device is configured to generate a braking force commensurate with a brake operation amount of a driver. At least one electronic control unit is configured to execute vehicle speed control for controlling a speed of a vehicle to a target speed by controlling a driving force and a braking force. The electronic control unit is configured to cause the brake device to generate an actual braking force corresponding to a total value of an additional braking force and an operational braking force when brake operation is performed during execution of the vehicle speed control. The additional braking force corresponds to a controlled braking force required by the vehicle speed control. The operational braking force is required through the brake operation.

A soft body system adapted to form the body and exterior surface of a Guided Soft Target for testing crash avoidance technologies in a subject vehicle is disclosed. The soft body system is adapted to be mounted atop a motorized Dynamic Motion Element (DME) and when so mounted is adapted to collide with the subject vehicle while the DME is moving. The soft body system includes a semi-rigid form with an exterior surface. The form is sufficiently yielding so as to impart a minimal force to the subject vehicle upon impact. The form may be shaped like a vehicle or a part of a vehicle. The exterior surface includes a side skirt made of radar absorptive material (RAM), radar reflective material (RRM) or a combination of both, which is positioned adjacent to the ground and constructed to prevent radar wave from entering the soft body system.

A vehicle control system for moving a vehicle to a target location is disclosed. According to examples of the disclosure, a camera captures one or more images of a known object corresponding to the target location. An on-board computer having stored thereon information about the known object can process the one or more images to determine vehicle location with respect to the known object. The system can use the vehicle's determined location and a feedback controller to move the vehicle to the target location.

A vehicular control system includes a camera and a control having a processor that processes image data captured by the camera to determine an approaching vehicle that is approaching an intersection forward of the equipped vehicle. The system determines projected path of the equipped vehicle. Estimated time to arrival of the approaching vehicle at the intersection is determined at least in part by processing of captured image data. Responsive to determination that the equipped vehicle will complete a turn at the intersection before the estimated time to arrival elapses, the system may determine that it is safe to proceed along the projected path of travel. Responsive at least in part to determination that the equipped vehicle will not complete the turn at the intersection before the estimated time to arrival elapses, the system may determine that it is not safe to proceed along the projected path of travel.

A vehicle control device includes a first control unit that executes, when an abnormality of a driver of a vehicle is detected, stop control, a second control unit that executes, when the vehicle is determined to have a risk of collision, deceleration control, a determination unit that identifies an object around the vehicle as a target candidate of the collision and determines whether or not there is the risk of the collision with the identified target candidate, and a setting unit that sets, when the abnormality is detected, an operation mode of the deceleration control to a special mode from a normal mode, the normal mode provided for cases in which the abnormality is undetected. The determination unit expands a range for identifying the object around the vehicle as the target candidate of the collision in the special mode as compared with the range in the normal mode.
